  1. Explain the function of computer hardware components

    Processor The processor more known as the CPU (Central Processing Unit) is a small chip; it is the main intelligence of the computer and controls everything that happens within the computer. The processor receives an output and input, and the processors job is to provide the correct output so that tasks can be completed by the user. The CPU gets instructions from the RAM (which is the input), reads and processes it and then sends back the data so that the relevant components can carry out the instructions. The speed of the CPU (central processing unit)

Conclusion analysis

Good conclusions usually refer back to the question or title and address it directly - for example by using key words from the title.
How well do you think these conclusions address the title or question? Answering these questions should help you find out.

  • To what extent does research support a link between stress and the immune system?

    "In conclusion to the experiments it is seen that stress is almost a definite cause of a suppressed immune system although it may not be the only reason that the immune system is suppressed.

  • To What Extent Was the Poor Law a New Poor Law?

    "The new poor law was a new poor law. Due to social, political, and economical circumstances, it was necessary for the time, as the old system was ineffective, inefficient, and bad for the poor. The new laws meant that there were tighter controls over the parishes and the poor; this made less chance of uprisings and rebellions. I agree similarly to the ideas of Digby; recent investigations on the Old Poor Law have produced convergent conclusions. They emphasise that relief under the Old Poor Law was essentially a response to population growth, under-employment, and low wages, rather than their causes as the Royal Commission's report alleged."

  • This research that I've done will discuss about the effectiveness of the Light Railway Transit (LRT) in Kuala Lumpur.

    "10.5 CONCLUSION In a nutshell, Hong Kong's Mass Transit Railway and Malaysia's Mass Transit have some similarity in term of technology and facilities. However, Hong Kong's Mass Transit Railway is more advanced than Malaysia's Mass Transit as they had started very early in the late 60's. Effectiveness of Malaysia's Mass Transit can be improved gradually and hopefully they can be as good as Hong Kong's Mass Transit Railway. APPENDIX 1. Map showing Hong Kong mass transit routes.
